Who Discovered Copper?

Who Discovered Copper?
Introduction Who discovered copper? Nobody knows. But evidence suggests that copper was the first metal ever discovered and used by man. Or at least one of the oldest. In modern day Iraq, archeologists once found a copper pendant over 10,000 years old. Unlike silver, copper is often found uncompounded in its natural state. So it is likely that humans learned to use copper first, perhaps along with gold and meteoritic iron. History of Copper Two of the world’s oldest civilizations made use of copper – Chaldea and Sumer. They used copper to make military equipment such as bows, arrows, spear heads and helmets. Archeologists have also unearthed small items like copper pins, harpoons blades and pots made of bronze (a copper alloy). Sumerian craftsmen made beautiful sculptures made from copper and mounted them on walls. The Imdugud Relief is a fine example of this. It dates from 3,100BC and shows an eagle with the head of a lion, holding a stag in each claw. Copper can be mixed with other...

Who Discovered Neon?

Who Discovered Neon?
Represented by the atomic number 10 and the symbol Ne in the periodic table, neon is another important chemical element with many practical applications. Under standard conditions, it is described as an inert and colorless noble gas. When used in neon lamps and discharge tubes, this element produces a unique reddish-orange color. Aside from these interesting details, it is also good to know something about its history particularly who discovered neon. The Discovery of Neon Who discovered neon? In 1898, English chemist Morris W. Travers and Scottish chemist William Ramsay discovered this all-important chemical element in the City of London in England. Aside from neon, they were also credited for discovering krypton and xenon. Ramsay chilled an atmosphere sample, which he then liquefied and warmed. As the liquid boiled off, he captured the gases and found three different elements, namely neon, xenon and krypton. Additional Facts and Other Interesting Information Years after the discovery...

Who Discovered Magnesium?

Who Discovered Magnesium?
Considered as one of the most abundant elements in our body, magnesium is an alkaline earth metal that plays an essential role in the functioning of biological polyphosphate compounds such as DNA, ATP and RNA. This element is also important to plant growth because it is the chlorophyll’s center. Aside from these, the element has other medical, agricultural and industrial uses. To know more about this element, it is best to start with the history of the discovery of magnesium. Historical Background Who discovered magnesium? Based on records, the metal was extracted and discovered in 1808 in England by Sir Humphry Davy. He extracted the element from the mixture of mercury oxide and magnesia with the use of electrolysis. Davy named the element magnium, however, it was later on called magnesium by other scientists. Even if Davy was credited for the discovery of the alkaline earth metal, Epsom salt, a compound form of the element was already used by a farmer in the country to heal rashes as...

Who Discovered the Slope Formula?

Who Discovered the Slope Formula?
The slope formula determines the position of a line with respect to its “x” and “y” coordinates. This mathematical calculation is the concern of Analytical Geometry which solves linear and geometric problem with the aid of Algebra. Thus, to the question who discovered the slope formula, it is necessary to look into who started Analytic Geometry. Rene Descartes 1596 Rene or Renee Decartes is the father of Analytical Geometry. He was a French mathematician, physicist, philosopher, and theologian. Many mathematics experts acknowledge him as the man who discovered the slope formula. He was said to have provided a method to solve the problem of lines and slopes in mathematics by his prowess in Algebra and Geometry. The basic slope formula is y=mx+b while the more complex point-slope formula is y-yl=m(x-x1). Because Descartes is the father of Analytical Geometry and this subject centers mostly on lines and slopes, he was the first to introduce solutions to slopes and linear problems....

Who Discovered Fractals?

Who Discovered Fractals?
Benoit Mandelbrot is usually credited with discovering fractals in 1975. Mandelbrot was the one who invented the word. He was also the first to represent them visually. But some facts about fractals were known to mathematicians as far back as the 17th century. Early Fractal Research A fractal can be described as a pattern that is repeated at every scale. It cannot be replicated by classical geometry. The concept of self similarity was first brought up by the philosopher and mathematician Lebinz in the 17th century. It wasn’t until 1872 before a function appropriate to be termed a fractal came into being. Karl Weierstrass showed an instance of a function that was continuous but could not be differentiated. This definition was improved upon by Helge von Koch in 1904 when he defined it as a Koch curve. A study of the facts about fractals will show it is now called the Koch snowflake. In 1915, Wallow Sierpinski created a triangle and a carpet. In 1938, Paul Levy came up with another fractal...
